Dendrosenecio Johnstonii
''Dendrosenecio johnstonii'', formerly ''Senecio johnstonii'', is a species of giant groundsel found in the middle altitudes of Mount Kilimanjaro in Africa. A recent botanical reclassification split off some species formerly in ''Senecio'', putting the giant groundsels in the new genus ''Dendrosenecio''. It also redefined the former species ''Senecio cottonii'', as a subspecies of ''Dendrosenecio johnstonii''. Both genera are in the family ''Asteraceae''. The giant grounsels of the genus ''Dendrosenecio'' evolved, about a million years ago, from a ''Senecio'' that established itself on Mount Kilimanjaro, with those that survived adapting into ''Dendrosenecio kilimanjari''. As it moved down the mountain, the adaptations necessary for the new environment created the new species, ''Dendrosenecio johnstonii''. Various subspecies are found on other mountains. Description ''Dendrosenecio johnstonii'' can be up to 10 meters tall, and grow to 40 centimeters (17 inches) or more in diameter ...

He was Librarian of the Herbarium, Royal Botanic Gardens, Kew from 1860–1890 and Keeper there from 1864–1890, and Professor of Botany at University College, London from 1861–1888. In 1864, while at UCL, he published ''Lessons in Elementary Biology'', based upon material left in manuscript by John Stevens Henslow, and illustrated by Henslow's daughter, Anne Henslow Barnard of Cheltenham. With a second edition in 1869 and a third in 1878 this book was reprinted until at least 1891. Oliver regarded this book as suitable for use in schools and for young people remote from the classroom and laboratory. He was elected a member of the Linnean Society, awarded their Gold Medal in 1893, and awarded a Royal Medal by the Royal Society in 1884. He married in 1861 and was the father of two daughters and a son, Francis Wall Oliver. In 1895, botanist Tiegh published '' Oliverella' ...
